If Naruto were betrayed in RWBY fanfiction, his values would be put to the test. Naruto believes in friendship and hard work. Being betrayed would make him question those beliefs. He might start to become more cynical, which would be a big change from his usual positive self. On the other hand, he could also use this as an opportunity to grow. He could learn about the different values in the RWBY world and try to find a new path. And perhaps, in the end, he would be able to forgive the person who betrayed him, but not without a long and difficult journey.
Perhaps Naruto would try to find allies among the outcasts in the Highschool DxD world. Since he has been betrayed, he would understand the feeling of being alone and might reach out to those who are also on the fringes of society. He could form a new group that challenges the existing power structures in the Highschool DxD universe, using his unique abilities and his unwavering will from the Naruto world.
Well, they might be shocked at first. The characters in RWBY are all about loyalty in their own group, so seeing a 'Betrayed Rose' would be quite a jolt. They could start to question the motives behind the betrayal, whether it was for power, love, or something else entirely.
In this fanfiction, perhaps there's a power struggle. Naruto, being a powerful ninja, could be seen as a threat to the RWBY world's power balance. So, the RWBY characters, out of fear or a sense of self - preservation, betray him. They might think he'll disrupt their way of life or take over their territory.
The RWBY team's reactions in the fanfiction when Jaune is betrayed would be complex. Ruby's reaction would be centered around hope and finding a solution. She'd likely try to talk to Jaune and see how he's feeling. Weiss would be outraged and demand justice for Jaune. Blake would be more introspective, perhaps relating the situation to her own past. Yang would be the most vocal and immediate in her anger. Their reactions would shape the further plot of the fanfiction, whether it leads to revenge, forgiveness, or something in between.
The story could explore how Naruto's power is affected by this betrayal. Maybe his godlike powers start to waver because his emotional state is so unstable. He might have to go on a journey to regain his confidence and control over his powers. Along the way, he could meet new characters who help him understand that not all relationships are doomed to end in betrayal. This would be a great way to develop Naruto's character further in the fanfiction.
Well, if Naruto is betrayed by Koneko in fanfiction, it could lead to a dark turn in Naruto's character. He might become more distrustful and cynical. Maybe he would start to question all his previous relationships and alliances. He could also go on a journey to find out the reason behind the betrayal and in the process, discover some dark secrets about the world he lives in.
One possibility is that Naruto becomes more isolated. After being betrayed by Akeno, he might find it hard to trust others. He could go off on his own to train harder and become stronger, vowing to never let such a betrayal happen again. This could lead to him unlocking new powers or abilities as he focuses solely on self - improvement.
They could lose their home. If the betrayal is by the village, they would no longer be welcome there. They'd have to find a new place to live, which could be a difficult task as they are being hunted. They might end up in a hidden, desolate place where they have to start from scratch, building shelter and finding food.
Hinata's betrayal could be a part of a bigger conspiracy. Maybe there are other forces at work in the ninja world that want to bring down Naruto. They use Hinata as a pawn. As the story unfolds, Naruto has to not only deal with Hinata's betrayal but also uncover the conspiracy and save the ninja world from a greater threat.
In such a fanfiction, it could be due to a misunderstanding. Maybe Naruto was forced into a situation where he had to act against the Yugioh world for the sake of his own village. For example, if there was a threat to Konoha that was somehow related to the Yugioh realm and he was given no other choice but to 'betray' them.
